.SH "NAME"
CLOSE \- close a cursor
.SH "SYNOPSIS"
.sp
.nf
CLOSE { \fIname\fR | ALL }
.fi
.SH "DESCRIPTION"
.PP
\fBCLOSE\fR
frees the resources associated with an open cursor\&. After the cursor is closed, no subsequent operations are allowed on it\&. A cursor should be closed when it is no longer needed\&.
.PP
Every non\-holdable open cursor is implicitly closed when a transaction is terminated by
\fBCOMMIT\fR
or
\fBROLLBACK\fR\&. A holdable cursor is implicitly closed if the transaction that created it aborts via
\fBROLLBACK\fR\&. If the creating transaction successfully commits, the holdable cursor remains open until an explicit
\fBCLOSE\fR
is executed, or the client disconnects\&.
.SH "PARAMETERS"
.PP
\fIname\fR
.RS 4
The name of an open cursor to close\&.
.RE
.PP
ALL
.RS 4
Close all open cursors\&.
.RE
.SH "NOTES"
.PP
PostgreSQL
does not have an explicit
\fBOPEN\fR
cursor statement; a cursor is considered open when it is declared\&. Use the
\fBDECLARE\fR(7)
statement to declare a cursor\&.
.PP
You can see all available cursors by querying the
pg_cursors
system view\&.
.PP
If a cursor is closed after a savepoint which is later rolled back, the
\fBCLOSE\fR
is not rolled back; that is, the cursor remains closed\&.
.SH "EXAMPLES"
.PP
Close the cursor
liahona:
.sp
.if n \{\
.RS 4
.\}
.nf
CLOSE liahona;
.fi
.if n \{\
.RE
.\}
.SH "COMPATIBILITY"
.PP
\fBCLOSE\fR
is fully conforming with the SQL standard\&.
\fBCLOSE ALL\fR
is a
PostgreSQL
extension\&.
